You haven't attached any code, but even if you had, I don't think it
would have worked.
> ["hi ryan 1","hi jeff 2"] becomes [["hi","ryan" 1], ["hi","jeff", 2]].
In Haskell lists are collections of elements of the _same_ type. In
your example "hi" and "jeff" are both String's, while 2 is an Integer.
The difference in types means they can't be placed in the same list.
Is this a homework exercise, or are you trying to learn independently?
If its homework, please read the homework help thing
(http://haskell.org/haskellwiki/Homework_help), and if you are trying
to learn on your own, you might want to read a tutorial or two first
